When diesel is used by
* ~30% of all cars
* all HGVs, coaches
* Trains
* Ships
Only other sector [as I can imagine] uses petrol is Aviation but that is a different grade fuel than cars'.
Of course we have 2-wheels and lawn mowers which still use petrol.
If price difference between petrol & diesel cars become narrower [or even equal], will people stop buying petrol cars?
PS: I never owned diesel cars myself though my next car is highly likely to be a diesel.
